I am trying to block a user from calling into our Skype for Asterisk build.

I can't seem a way to block a user from the CLI, however I did login to the account using Skype for Mac and blocked the user there. However the user is still able to call even though he/she is blocked (from the mac app)

Does the block only apply when logged in with the Mac App? Or should the block be global?

Can someone point me in the right direction to get this user blocked from calling in globally?
